Which time-zone meaning are we using?
Eastern Time
ET follows America/New_York. On your selected date it uses UTC−05:00 (EST). Its offset can change when the regional clock rules change.
Fixed alternatives: EST (UTC−05:00) · EDT (UTC−04:00). These labels keep their stated UTC offset throughout the year.
ONE CLOCK TIME. THE WHOLE YEAR.
